Router with multiple static IPs

Hello and thank you for taking the time to read my message.

I am looking at setting up a small LAN with a few print servers using
DSL. I have ended up with 5 public IP addresses.

Before now I have only had a single IP address using a Linksys Router
for internet access. I then setup port forwarding within the Linksys
to send data to my single print server.

The connection I am looking into is an ADSL connection which uses
PPPoE. I have checked my Linksys router and it does support the
PPPoE. The router (Netopia I belive) that comes with the service is
has 4 ports on it. I was planning on setting up the Linksys Router to
the new router using the PPPoE feature of the Linksys, and a single
public IP address - which would give me a basic setup of what I
currently have.

I was wondering if anyone had any suggestions as to how I would be
able to use the other connections for other print servers. I was
looking into something like ClarkConnect to allow me to setup a
firewall machine, but I didn't know if I could setup 2 or more public
IP addresses going in and ClarkConnect direct the addresses to a print
server on my LAN.

Before I ask the next question, remember I am very new to ADSL. Would
it be possible to setup the public IP directly to the print server
without using any kind of PPPoE?

Any advice would be greatly appreciated!
Mike

If the Netopia, or whatever you got from the ISP, is a modem/router, you
would NOT be able to use the Linksys without it, it would need a DSL modem
to connect to the phone line, and I do not think any Linksys routers can
handle more than 1 public IP. Although, you could always use the Linksys
behind the modem/router to NAT any equipment that does not need a public
IP.

Yes, the ClarkConnect connected to your ISP's modem/router could handle
multiple public IPs. I am doing similar with a 255.255.255.248 wireless
portion of my wired LAN, using proxy_arp so the LAN ethernet answers arp
requests for the wireless IPs.

Your ethernet interface facing the modem/router would have netmask
255.255.255.255 with host route and default route to modem/router, and
proxy_arp enabled (so modem/router can find your other IPs).

LAN interface for your other public IPs could have same IP with netmask
255.255.255.248. That would leave 4 public IPs available.

Whether your connection uses PPPoE or not, that is likely handled by the
modem/router from your ISP. So the only issue might be whether you put
the print server directly on the modem/router, or behind the ClarkConnect
box for better access control.
